Ramubs is a 300-400Mhz 16bit DDR serial style bus. And is used by some P3 chipsets and the only current P4 chipset.

DDR is a 100-133Mhz 64bit DDR parallel style bus. And is currently only used on a few athlon chipsets.

i would always go with ddr (for now)

1)its cheaper than rdram
2)rdram isnt much faster
3)it goes with amd systems (cheaper & faster than p4)
